In this masterwork of an authentic spirit person (Thomas Berry), Buddhist teacher and anthropologist Joan Halifax Roshi delves into the fruitful darkness - the shadow side of being, found in the root truths of Native religions, the fecundity of nature, and the stillness of meditation. In this highly personal and insightful odyssey of the heart and mind, she encounters Tibetan Buddhist meditators, Mexican shamans, and Native American elders, among others.
